Application filed February 14, 1921.

To all w ham it may concern Be it known that I, VVILLIAM T. MCGRAW, acitizen of the United Eitates of America, residing at Detroit, in thecounty of Wayne and State of Michigan, have invented certain new anduseful Improvements in Account-Filing Cabinets, of which the followingis a specification, reference being had therein to the accompanyingdrawings.

The invention relates to filing cabinets of that type provided with aplurality of hinged trays which are stored within the cabinet invertical position and may be successively turned down into horizontalposition when the cabinet is open. Each of these trays is provided witha series of pockets, in which the individual accounts or sales slips areplaced, the pockets being designated by a number or other indicatingcharacter for reference to an index, preferably arranged on the cover ofthe receptacle.

Cabinets of the general type above referred to havebeen heretoforeconstructed and the present invention consists in certain improvements.with particular reference; first, to the construction of the trays andthe means for detachably mounting the same within the cabinet; second,the construction of the outer casing or cabinet, which is such as to beeasily and cheaply manufactured and to be completely fire-proof; andthird, in various details of construction as hereinafter set forth.

In the drawings: I

Figure l is a perspective view of the cabinet in open position;

Figure 2 is a cross-section through one side of the cabinet with thetrays removed;

Figure 8 is a perspective view of one of the trays;

Figure 4 is a perspective view showing one of the guides in which thetrays are hinged;

Figure 5 is a perspective view of a portion of one of the trays.

A is the outer casing or cabinet, which is formed with sides B and B,back C, a hinged top D, and a hin ed front E, the lat ter forming, whenturned in horizontal position, a desk or support for the trays F. Themargin of each tray is reinforced by edge strips J, preferably ofchannel section which are attached to each other and to the portion G,preferably by spot-welding. For holding the sales slips, clips K areprovided, each consisting of a securing portion K Serial No. 444,799.

which is spot-welded or otherwise secured to the bottom of the tray, anda tongue portion K hinged to the portion K and resiliently pressedtoward the tray by a spring K The clips K are placed in pockets onopposite sides-of the tray, but are arranged to extend in oppositedirections so that those on the front side, when the trays are invertical position, will have the tongues extend upward, while those onthe rear side extend downward when the trays are in vertical positionand inward or toward the cabinet when the trays are in horizontalposition. To hold the pads from displacement in the pockets having thedown-turned tongues, stops L are struck out from the blank G, asindicated in Figure 3.

The trays constructed as just described are detachably mounted in thecabinet, so as to be capable of swinging from vertical position tohorizontal position. This is preferably accomplished by attaching toeach tray adjacent to the inner edge thereof and upon opposite sides thepintles M which are engageable with bearings in the sides of the casing.These bearings are I preferably formed of pressed sheet metal members Nwhich are secured to and offset from the inner faces of the cabinetsides, extending obliquely upward from front to rear. In these members Nare formed the slotted bearings for engaging the pintles and the memberI on one side of the cabinet is also provided with entrance slots O,which extend to the edge of the member. The arrangement is such thatwhen the pintles are engaged with the slots, the trays may be swung fromvertical to horizontal position and in each position will lie inparallelism with each other. The fact that the bearings are slotted permits of automatic adjustment to compensate for any differences in thetwo positions of adjustment or for any displacement occasioned by thethickness of the pads in the tray pockets. When in vertical position,the trays are held from accidental displacement by friction clamps Parranged upon oppo site sides of the cabinet, these being preferablyformed of bowed steel strips P having facing strips P of brass or othersoft metal.

The cabinet is formed of sheet metal with hollow walls within which arearranged fireproof heat insulating material. such, for instance. ascellular asbestos board. preferably comprises the outer and inner platesQ and Q. spaced from each other and Each wall connected at the margin bystrips Q of channel section. The structure is further reinforced bychannel strips R secured to the outer side and arranged parallel Withthe margin thereof and centrally across the same.

By reason of the inclined arrangement of the members N, the trays willbe arranged in stepped relation, both in horizontal and in verticalpositions of adjustment. This will expose index characters, which arepreferably placed on sheet metal clips U secured by bending about themarginal strip of the tray. The clips are also indexed and the markingis formed on sheet metal strips V which are bent about the centralportion of the tongues K the edges of Which are notched to receive andhold the strips from displacement.

The space Within the cabinet beneath the trays may be utilized forstorage pockets, as indicated at W, While the frame is strengthened bybraces or gussets X.

Une of the advantages of the construction as above described is that itis made up of sheet met 1 parts, all of which are easily formed and aresecured to each other by spot-welding. This gives strength and afire-proof character to the cabinet, While the heat insulation in thehollow Walls will protect the contents oi the cabinet from, burning.

The engagement of the pintles M With the slots 6 will, as beforedescribed, permit of lateral displacement of the trays, so that theywill arrange themselves in parallelism, While the entrance slots Ufacilitate the neaaois quick engagement and disengagement of the trays.To avoid accidental disengagement when the trays are being disengaged,this entrance slot 0 intersects With the slot 0 intermediat the endsthereof, so that notches or recesses O are formed at the outer ends ofthe slots 0, which Will hold the pintles from accidental displacement.

What I claim as my invention is:

1. Inafiling cabinet, the combination With a casing, of a series oftrays arranged Within said casing in stepped relation, pintlesprojecting from each tray forming hinged. members therefor and pressedsheet metal members secured to the inner Walls of the casing, saidmembers having spaced slots extending transversely thereof for engagingthe pintles, and the member on one side having entrance slots extendingobliquely from said spaced slots for said pintles, said entrance slotsintersecting the spaced slots intermediate the ends thereof to preventaccidental disengagement of the pintles.

2. In a filing cabinet, the combination with a casing, of a series oftrays arranged therein in stepped relation, pintles forming hingedconnections for said trays, and inclined cooperating bearings secured tothe Walls of the cabinet and having parallel in clined slots forengaging the individual pintles and permitting automatic adjustmentthereof, one of said bearings having entrance slots intersecting saidinclined slots intermediate the ends thereof.

In testimony whereof I aflix my signature.

WILLIAM T. MGGRAW.
